PICTURE CORRECTING APPARATUS FOR USE WITH IN-LINE TYPE COLOR PICTURE TUBE

摘要

In a deflection yoke of self-convergence system for use with in-line type color picture tube, the intensity of a magnetic field, which causes the change in impedance of coils of saturable reactors respectively connected in series with two horizontal deflecting coils, is increased so that the variation rate of the inductance expressed in terms of a differential coefficient has the relationship of theta e/ theta m
